CHECKING BOLT TORQUE

specied in chart unless otherwise noted. Check tightness of bolts periodically, using bolt torque chart as a guide.
Replace hardware with the same strength bolt.
7.2 BOLT TORQUE
Torque gures indicated above are valid for non-greased or non-oiled threads and heads unless otherwise specied.
Therefore, do not grease or oil bolts or capscrews unless otherwise specied in this manual. When using locking ele-
ments, increase torque values by 5%.
